What would the speed of a dropped object be after 4 seconds?

I don't really understand this, can someone explain it to me, please?

It depends on the size shape and weight of the object

It could be a trick question, for example, if you dropped an object onto a table that was immediately below, the object might hit the table and come to a standstill before even one second has passed. But it probably has more to do with the fact that Earth's gravity continues to pull an object down towards it with 'accelerating velocity' (until the object reaches its terminal velocity.)

Isn't the rate of acceleration on Earth like 9.8 meters per second? So 39.2 meters per second? I think? I don't have a calculator on me.

Wait... Let me get this straight... You sent this message from a device that can browse the web and you are telling me you don't have access to a calculator?

Yeah, but I would have to close the window and type it all out again.

You also got the math right!

depends on what the height is that its droppped from and how much it weighs..

For the sake of what you're probably doing, let's forget air resistance. So, EVERY SINGLE item dropped, again, without including air resistance, falls at 9.8m/s/s. So, 9.8x4=39.4m/s. So, that is your answer!
